The council recommends
On: "Should I buy a house or rent?"
Top pick
Rent for Now and Invest the Surplus
Default to renting while running a detailed local rent-vs-buy calculator on your target market. Only consider buying if you plan to stay in the home for at least 5 to 7 years and have a solid 20% down payment plus an emergency fund. Until those conditions are fully met, invest your surplus cash into broad-market index funds.
Runner-up
Buy a home only if your local price-to-rent ratio is below 15 and you are firmly anchored long-term.
Wildcard
Rent your primary residence for flexibility while purchasing a cash-flowing rental property elsewhere.
Best time
Actively rent now, review your local price-to-rent ratio annually, and buy only when your horizon clears 5+ years.
88%
aligned
All three experts recommend defaulting to renting unless strict financial and long-term residency criteria are met.

Where they agree
✓Renting preserves crucial geographic flexibility and eliminates upfront illiquid friction costs.
✓Buying requires staying in the property for a multi-year horizon to amortize heavy transaction costs.
✓Local market metrics like the price-to-rent ratio must dictate whether purchasing is mathematically sound.
Where they diverge
↔Experts disagree on the minimum break-even time horizon, ranging from 5 to up to 10 years.
↔Google explicitly advises directing all surplus rental savings into broad-market index funds.
↔Anthropic emphasizes personal calculator inputs rather than firm down-payment requirements like OpenAI.

Why is the break-even horizon 5 to 10 years?
It really comes down to math and "friction costs." When you buy and eventually sell a home, you lose a massive chunk of money to non-recoverable expenses.
Here is why it takes so long to dig yourself out of that hole:
1. High Transaction Costs (Round-Trip Friction): Buying costs around 2% to 5% in closing fees, and selling typically costs another 5% to 8% in agent commissions and transfer taxes. That means your home has to appreciate roughly 8% to 10% *just to break even on fees*.
2. Front-Loaded Mortgage Interest: In the first 5 to 7 years of a standard 30-year mortgage, the vast majority of your monthly payment goes toward interest, taxes, and insurance—not your principal balance. You build equity very slowly at first.
3. The Opportunity Cost of Your Down Payment: From my perspective, this is the biggest factor. Tying up tens of thousands of dollars in an illiquid house means that capital isn't compounding in liquid broad-market index funds (like the S&P 500).
It simply takes 5 to 10 years of steady property appreciation and slow debt paydown to outpace what you would have earned by renting cheaply and investing the difference in the market.
